Petunia plant named ‘Keipamiphihas’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Keipamipihas’, characterized by its upright and mounded plant habit; vigorous and freely branching growth habit; freely flowering habit; white and light purple bi-colored flowers; long flowering period; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘Keipamipihas’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Keipamiphihas.

The new Petunia is a product of a planned breeding program conducted by the Inventors in Sawara, Chiba, Japan. The objective of the breeding program is to create new Petunias with numerous flowers with attractive flower colors.

The new Petunia originated from a cross-pollination made by the Inventors in September, 2001 of two unidentified proprietary Petunia selections, not patented. The new Petunia was selected as a single plant from the resulting progeny of the cross-pollination by the Inventors in a controlled environment in Yokaichi, Shiga, Japan.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Sawara, Chiba, Japan since September, 2003 has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Keipamipihas have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Keipamipihas’. These characteristics in combination distinguish ‘Keipamipihas’ as a new and distinct Petunia cultivar:

-   -   1. Upright and mounded plant habit.     -   2. Vigorous and freely branching growth habit.     -   3. Freely flowering habit.     -   4. White and light purple bi-colored flowers.     -   5. Long flowering period.     -   6. Good garden performance.

Plants of the new Petunia differ from plants of the female parent selection primarily in flower color as plants of the female parent selection have solid light purple-colored flowers.

Plants of the new Petunia differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are taller and broader than plants         of the male parent selection.     -   2. Plants of the new Petunia have larger flowers than plants of         the male parent selection.

Plants of the new Petunia can be compared to plants of the cultivar Keipabukas, disclosed in U.S. Plant Pat. No. 14,748. In side-by-side comparisons conducted in Sawara, Chiba, Japan, plants of the new Petunia differed primarily from plants of the cultivar Keipabukas in flower throat and tube coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Petunia.

The photograph at the top of the sheet comprises a top perspective view of a typical flowering plant of ‘Keipamipihas’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical flowers ‘Keipamipihas’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Sawara, Chiba, Japan, in 24-cm containers for about three months in an outdoor nursery during the summer with day temperatures about 27° C. and night temperatures about 20° C. Plants were pinched one time in the early sumer.
